Public ISBD Titre de série : U.S. Geological survey water-supply paper, 2370 Titre : Soil water and vegetation responses to precipitation and changes depth to ground water in owens valley, California Type de document : texte imprimé Auteurs : Sorenson, S. K. ; Dileanis, P. D. ; Branson, F. A. Mention d'édition : U.S Department of the interior Editeur : U.S Department of the Interior Année de publication : 1991 ISBN/ISSN/EAN : CI-07609 Note générale : Vegetation on the floor of avens valley, California, is composed predominatly of phreodophytic desert communities that are adapted to small quantity of precipitation and alkaline soils. These plant communities are believed to be dependent on the continuing presence of a shallow water table. Maintaining existing plant communities is important to preserve the environmental quality of the valley. Proposals to pump additional quantities of groundwater from the valley for export to city of Los Angeles caused concern about the effect of pumpiny on the existing vegetation and how the plants would adapt to short -or long-term declines of the shallow water table...
